blueprint

[wraith loom]

when the actor is destroyed

and just draw from that variable

[timid yarrow]

which variable am i going to use?

[wraith loom]

what kind of mesh is it?

[timid yarrow]

it's static mesh

i did something but it didn't work

i used integer

[wraith loom]

Try static mesh variable

[timid yarrow]

thanks i'll try

[lyric rapids]

how do i refrence the color and opacity of this text widget in a blueprint

[floral stump]

https://www.youtube.com/watch?v=hPd92ZFKy0E

[lyric rapids]

so how would i make the alpha lerp from 0 to 1

[faint pasture]

however you want

timeline

tick

I think widgets get their own animation system

[lyric rapids]

i dont know how to refrence the alpha tho

[faint pasture]

get a ref to the textblock, right click it, dig around

[lyric rapids]

right click where

theres no refrence

[faint pasture]

check that

[lofty rapids]

while loop

[lyric rapids]

yeah it doesnt affect it all

[faint pasture]

why do you have a while loop

that while loop will run all in 1 frame

you'll see nothing change over time

start with a timeline if that's available for widgets, or otherwise use this
https://docs.unrealengine.com/5.2/en-US/animating-umg-widgets-in-unreal-engine/

[lyric rapids]

can i not put something like a yield return null in the loop somehow

[faint pasture]

why do you have a loop on tick

don't

[lofty rapids]

just use the tick or a timer

[faint pasture]

just Tick -> change the variable
or
Event -> play timeline -> timeline update -> change the variable

for your use case you'll want timeline or the animation track approach

tick would be used for something that continuously updates "chasing" a variable.

[lyric rapids]

ok i changed it however its still not working

which means the color and pacity refrence is not the one that changes the text color

[lofty rapids]

so from my understanding this runs for each one of the gets ?

the parse into array runs each time ?

[versed sun]

called once per White Exec pin i believe

[lofty rapids]

well the parse into array is pure

i was here the other day and someone posted this https://celdevs.com/unreal-engine-and-the-hidden-pitfalls-of-blueprints/

and it made me rethink the use here

i could cache it, but i just made it in c anyway

but i just wondering if it ran for every get

seems like it based on the post

[main lake]

It works perfectly, thank you so much 🙏

[slim trail]

Hello, I'm having an issue with setting constrained components using a physics constraint. I have an object that I want to attatch with a physics constraint to my mesh, and I have selected a bone as part of the mesh component. But no matter what bone I chose, the object seems to teleport to a specific point in the floor that is not related to my mesh

im not sure how i would go about solving this

if I play as another mesh like Manny, it works fine, but the point on that spot in the map is still highlighted

[tribal gazelle]

I'm having trouble trying to work out how to get this GetPlayerHUD reference. I can't seam to find it anywhere but would it be an actual function somewhere? I need to change the reference?

[lofty rapids]

looks like a pure function

are you saying because it's red, you need the right thing ?

[tribal gazelle]

Well I am just not sure where to find the node or section to change the reference, as I need to change it.

Reference viewer is disabled

[lofty rapids]

how did you connect it in the first place ? and what is the other node ?

[tribal gazelle]

It's a template asset which I am changing the UI references to a new one.

[lofty rapids]

is it red because you changed the pin ?

[tribal gazelle]

It's red because I am in the process of changing the references to fix the errors.

[lofty rapids]

so you can refresh node for one thing

might help

[tribal gazelle]

But the reference is the old one

Refresh node does not do anything

[lofty rapids]

so break the link, how did you get it connected ?

i would think you changed the node ?

i'm not sure what your saying you have a function that returns something, thats not the right thing you need now ?

[tribal gazelle]

It's referencing the old UI "W_HUD" need to change to "WBP_MainHUD" but I think I am just going to rebuild the widget instead of making a new one. Will eliminate the need for this entire process.

[lofty rapids]

well you probably will have to change the output of the function

you will probably see where it returns W_HUD

and maybe change it

looks like a function you made ?

or you downloaded the stuff and your changing it ?

if you changed the node on the right to take a different class now in HUD, then you would need to check that function and return the one.

[quick imp]

Has anyone set an animation blueprint in a datatable and then pull it from that datatable and set it to the skeletal mesh in a character blueprint?
I'm trying to setup a characters datatable where a skin and animation can be set, then on spawn of the character. It pulls all that data and sets it. But I am having issues pulling the animation blueprint from the datatable

[undone bluff]

you probably just need to right click refresh it or File > Refresh all Nodes

if that doesn't work you can try deleting the variable and replacing it

or go manually over each instance its used and swap it out

hover your mouse over pins to see their types

[tribal gazelle]

Yeah refreshing does not work, going to make my life easier and instead of backing them up and making new ones, I'm just going to use them as is, which will eliminate this entire process.

[thin panther]

just use source control instead of this odd backing up workflow

[iron furnace]

Does anyone have a good basic tutorial for implementing a doom/retro style weapon system? I just need something really basic, and everything ive found goes super in depth or uses C++

[trim matrix]

this skechfab 3d model only has 1 texture? how might i bind it to the model???

[faint pasture]

WHat exactly makes it retro?

[lunar sleet]

Clearly not the implementation, because those old boys had to get their hands dirty in C

[austere ingot]

does Get All Actors of Class check EVERY ACTOR in the world to find the classes or does it already know the classes?

if i have 5000 actors and class Xmpl exists 10 times, does Get All Actors of Class Xmpl only grab the 10, or does it iterate every actor in the world?

and would get all actors with interface be faster?

[lunar sleet]

Iirc it only checks every actor of that class, hence the filter

[lunar sleet]

This function has its uses but there are usually better ways to go about things

Interface msgs are not necessarily faster but can be less expensive since they don’t necessarily load the actor right away. But you shouldn’t try to optimize prematurely.

[echo wren]

I am having a hard time making a space ship do what i want. Basically i have a pawn with a spring arm/camera that tumbles around it with the mouse. right now the root moved with Add Force on the forward backward. What i would like is to have the rotation of the root/pawn/sphere match the rotation of the controller/camera. i think doing this by using "Add Torque" is a good way.. but i cannot seem to impliment it. SHould i keep trying this methos or just use to add control imput? I was it to be a spaceship and like keep rotating or moving if no opposite force is added (which right now works with forward backward Add FOrce)

i can get the difference of the two rotations (red - blue = green) and then when i feed green into add torque, the destination cube goes nuts

so as blue moves towads red, then green should get smaller, but its like the torque is not applying correctly

[short phoenix]

Is there a naming standard for Blueprint interface?

[echo wren]

i have simplified it to 2 cubes. when i move the left one, source , i want the right one to apply torque or force or something (thats what i dont know how to do correctly) so that it wants to match the left one.

[surreal peak]

You mean the asset?

[short phoenix]

Yeah like WBP_Foo.

I'm using WBP_IFoo but I didn't know if there's something specific.

[surreal peak]

BPI_ fwiw. But you are free to do what you find good as long as you stick to it

[echo wren]

https://docs.unrealengine.com/5.3/en-US/recommended-asset-naming-conventions-in-unreal-engine-projects/#BI_

[short phoenix]

Thanks everyone.

[echo wren]

So BI_

[surreal peak]

Yeah we do BPI

As long as you stick to it, it doesn't really matter

There is also Allar's style guide that you should find via Google.

You can take inspiration from that too

[hexed cloak]

Get All Actors With Interface is far better than Get All Actors Of Class because it doesn't create a hard reference wherever you're doing the call.

From my testing, it doesn't call every actor, but don't have hard evidence of that besides it not completely shutting down when using it sparingly in a huge world with 10k+ actors.

I typically use Get Actors With Interface for doing what you're trying to do.

[surreal peak]

GetAllActorsOfClass uses a hashed map to find the classes. It's not as bad as everyone says but still somewhat shows a bad setup. I don't think I have a single GetAllActors node in any of my recent projects

[lunar sleet]

You could also navigate to native and open up the code under those nodes so you can see and know for sure. I haven’t used get all actors with interface before, I was talking about interface msgs vs get all actors of class

[surreal peak]

Having the Pawn use ControlRotation and modifying that via AddControlInput could totally work

[lunar sleet]

And also you replied to the wrong person I think

[lunar sleet]

Same, it’s more of a crutch for beginners imo, aside from a few exceptions

[surreal peak]

99% of the time, having a Manager Class/Component/Subsystem that has a list of those actors which add themselves to it and remove themselves from it via BeginPlay and EndPlay or similar is enough and overall allows for more control

[hybrid blaze]

What is the best way to have a main weather cycle and have it affect different parts of the game like foliage, terrain, npc mood. Is it better to have it a static actor blueprint that runs the whole time the game is up or what is better?

[spark steppe]

yes make it an actor

and for materials you would use a material parameter collection which you update within that actor

[hybrid blaze]

It would also require to have ability to retrieve how much time as passed inagme if the user closes and opens it later too, will that be possible too?

[spark steppe]

then you can use the values from the collectin in your materials

[hybrid blaze]

Ok

My confusion was there is a separate game instance that runs by default and heard few places that stuff like this is put there , but If I keep adding all things like this to the game instance, it could be very cluttered later on

[spark steppe]

that's why you would make it an actor

[hybrid blaze]

Got it

Good to know my logic is correct

[hexed cloak]

Was just replying to the convo sorry haha @austere ingot was definitely aimed more at their question

[random pulsar]

is it always like this ,when a solo developer no matter of experience makes a game,he thinks its a trash?

Or there is a point in experience if you reach it you consider your games good?

[short phoenix]

How do I call a superclass' On Initialized event? It looks like it doesn't get invoked due to my child class having one.

Ahh "Add Call to Parent Function." Wow that's wild.

[lyric rapids]

is there a reverse of that function add to viewport like remove from viewport or something because i cant seem to find it

[gentle urchin]

Remove from parent

[lyric rapids]

thank you

the print string is calling so i dont know why remove from parent isnt working

[gentle urchin]

Have ypunadded several of them?

I prefer letting widgets like that maintain their own lifetime

[lyric rapids]

ive only added one

[gentle urchin]

Are you 100% sure

[lyric rapids]

yeah i only call add to viewport once in my level blueprint

[gentle urchin]

During what event

[lyric rapids]

custom event in tick thats on do once

[gentle urchin]

😅

Dont use tick for this

Theres beginplay

[lyric rapids]

no cause i dont want it called at the start of the game

[gentle urchin]

Then call the custom event when you want it to

Gating it on tick is weird

[lyric rapids]

I am after a branch then a switch node

[gentle urchin]

Still weird

If you do PIE

And open the widget in question

When its spawned on screen

You can see the object selector in the top bar menu

Check how many entries there are

[random pulsar]

i have to make the player know what he need to collect and i have a lot of collectables,i thought about changing material ,but there are a lot of materials in the scene,i added a point light in the parent but it looks trashy

any sugestions?

[gentle urchin]

Some sort of vfx flair

[versed sun]

Overlay Material

[gentle urchin]

Visual effect

Hzd uses sole vfx when in proximity

You can see it next to the target

With the triangle on top

Showing their 'category'

[random pulsar]

oh thanks,idk visual effect looks complicated,but a material is fine for my level 🙂

[gentle urchin]

Highlights is a common thing

Not very complicated to setup

[random pulsar]

i found this one,which i am trying already

[random pulsar]

done 🙂

[gentle urchin]

Neat

[thick prairie]

Hey guys. Can someone give me a few ideas why some UI elements are semi-transparent in playmode while they should be opaque as it's shown in those editor screenshots (the ones with with skill name and black background). Also there's some render order issue.

Ok, I managed to fix the render order, but i have no idea why they're transparent in playmode while they should be solid black :/

[versed sun]

is solid black 0,0,0,0 or 0,0,0,1 ?

[thick prairie]

@versed sun 0,0,0,1

Every parameter with color information i could find, has alpha set to 1

[crude cradle]

Hey! Is there a good way to modularise blueprints for gameinstance?
In c++ we have subsystems, but is there some equivalent to it in Blueprints? I guess separate event graphs and functions in categories work - but I was thinking of splitting logic into a separate blueprint alltogether
Is there a common good pattern for it?

[random pulsar]

i thought i am a genius and can cheat a little and turned out i am dumb not genius)

i wrote this in every child overriding the overlap event,so if ineed to change smth i have to do it in every child.And this is because i was lazy and didnt know how to make an inventory system

and these are only the first ones,i plan to add more,and also 7 different levels💀

[gentle urchin]

Do it in the common parent

[random pulsar]

this is how it works now

[random pulsar]

yeah there is a way definately,but i don't see it 🙂

[random pulsar]

are you free now,can you join the vc?

[gentle urchin]

If there is none , create one

No

Im never free 😅

Tied down to the chains of responsibility and parenthood

[random pulsar]

so the problem is i need to know what child i am overlapping with,how can i do this in parent?

[gentle urchin]

You dont need to know which one

Any child of parent has the overlap event with shared functionality

[gentle urchin]

Wrap it up in function and let children override that function if they deviate from the standard

[random pulsar]

yeah but this setup is not good,i need to display how many plants he need to collect ,each one now has its own variable in player

[timid yarrow]

I don't know anything about multiplayer. When I increase the number of players up to 2 and play, I can move on server but not on client. The client is like stuttering or something. I don't know anything about replication. How do I fix this?

[thick prairie]

Ok, I manage to fix my transparency issue - my canvas panel ended up i some weird place, totally outside of my UI elements

[gentle urchin]

The parenr has a variable for the type. Each child overrides with their specific type / name / whatever

[random pulsar]

so i dont need the amounts of objects in player?
i need to make one in the parent food and then what?

[gentle urchin]

You do need amounts in the player still

[random pulsar]

i dont get it

[sand yacht]

is there a way to only open a level after compiling shaders has finished?

i dont want players to be looking at an untextured world for half a minute when they load into the game

[frosty heron]

How can u be compiling shader in package game anyway

If u r doing stand alone test u can ignore that bit

[undone bluff]

I assume there's still no blueprint accessible loading screen functionality

Compiling shaders is iffy, games tend to do that on the fly or precompile on startup

[rain lotus]

I created a new project with all the updated assets I intent to use. Migrating over the custom files from my old project, is it safer to override or not?

ideally I would like all the custom child actors to link to the latest assets (not override) if it's safe

[frosty heron]

There isn't any bp that do anything about loading screen. Cpp only

In package game u should never see compiling shader. That is something that gets compiled before u even run the game

U only see it in standalone editor test. Disregard that

[undone bluff]

No it's hardware specific afaik

[frosty heron]

For?

[undone bluff]

If you know the target hardware you can have shaders compiled for it

[frosty heron]

I know nothing about this. It's certainly possible to compile shader at run time but that will require intervention imo

In case of unreal out of the box, if u package a game u should never see compiling shader

[undone bluff]

Shaders need to be compiled differently for different gpus

[frosty heron]

Do you have anything I can read or able to replicate it?

[undone bluff]

For most games it should be compiling on demand as needed

Without too many hitches

[frosty heron]

It should be compiled before u even run your game

Imo

[undone bluff]

Yea but this

[frosty heron]

Got source? I am interested

[undone bluff]

I'll find something just a sec

[frosty heron]

Cuz I can't get it to show up with my laptop or pc

[undone bluff]

https://docs.unrealengine.com/5.3/en-US/API/Runtime/Engine/FShaderCompilingManager/

not exactly what you asked for but still useful

Submitjobs function lets you request async compile of shaders

[frosty heron]

Ye but I'm saying I think it will require intervention, not something out of the box in unreal

[undone bluff]

https://docs.unrealengine.com/5.3/en-US/API/Runtime/Engine/FAssetCompilingManager/

GetNumRemainingAssets

[frosty heron]

Prob useful for games like modern warfare 2 when one need to compile shaders at run time

[undone bluff]

Returns the number of remaining compilations.

[frosty heron]

But out of the box, is that the default behaviour?

[undone bluff]

default behaviour is compiling shaders as they are loaded into memory I'd assume but I'm not 100% sure

I was hoping there was a docs page on this topic

[frosty heron]

Well can't say I understand how things work

It's just I never see the notification unless in stand alone pie test

[undone bluff]

oh found something

https://docs.unrealengine.com/5.3/en-US/shader-development-in-unreal-engine/

check the Shader Compilation section

[frosty heron]

I will read that. Ty

So it's run time then using the streaming method u mention above

Never know that

Must be really fast in packaged game or it already have cached shader map

[undone bluff]

well shaders only have to compile once so that definitely helps

I remember reading about some games just straight up spawning in stuff in the main menu to force shader compilation

honestly it is something you do notice

I remember Elden Ring having some hitches when some assets load in for the first time

[frosty heron]

👍

[sand yacht]

aah okay okay thanks

[silent stag]

hey , when i play game in small screen my widgets stay same size

[timid yarrow]

What's wrong on this code

i tried to replicate it

but it didn't work

[lofty rapids]

i feal like that custom event is using an axis value from the other event, not sure how that works

maybe its cache from the last value pulled out ?

[timid yarrow]

which custom event?

[lofty rapids]

or maybe it's not custom but multicast movement

when does that fire ?

[timid yarrow]

it fires when a movement key is triggered

w a s and d

oh sorry

[lofty rapids]

so you run the event on triggered ?

i'm not sure what that axis value would be at the point that other event runs

because your pulling out of the other event

[timid yarrow]

i am trying to make the multiplayer thing

i am going to try another thing

[lofty rapids]

i have not done multiplayer yet so idk, just looks weird like that

[timid yarrow]

oh ok

thank you anyway

[timber crystal]

Hello guys i hope every body is weeeeeeeeeeeellllll

i have a ezy to fix problem 😄

screenshots follow

thats my tutorial tirgger box but why it stops my enemys when collision is just on overlap? and not on block

more images follow

thats the enemy

[thin panther]

because you're checking for an overlap.
you've said "set this thing to overlap only, and when it overlaps do X"

[timber crystal]

Can you explain this to me in a little more simplified terms? My English isn't the best
I don't understand exactly how should I set the collision 😦 sorry

ok i got it

thanks

[zealous fog]

Anyone know the differnce between these two nodes?

[lofty rapids]

constant "Tries to reach Target at a constant rate."

the normal one "Tries to reach Target based on distance from Current position, giving a nice smooth feeling when tracking a position."

[chilly oak]

I want to know whether there is a bp script for the recoil system of i follow virtus videos for fps shooters using tps template

[zealous fog]

Thank you!!

I had read the tooltips but read the same one twice I think

lol

thanks

@zealous fog i read in your profile that you are a game design student,from what country and what university?I am asking cuz i am also at game design

[timid yarrow]

How do I make any game multiplayer in blueprints?????

So how do i make a roll a ball type game multiplayer???????

[rare moss]

What is a roll the ball type game

[timid yarrow]

There is a static mesh that you can move it by adding impulse to it

(My static mesh is not ball, a chair by the way)

[rare moss]

Anyways multiplayer works by syncing (as few as possible) things between clients so the game looks the same for everyone

[neon hedge]

Replication ^

[timid yarrow]

But i can't make it

[rare moss]

So you have to replicate things
I'm no unreal expert but I've seen some checkboxes somewhere while watching others which allows you to replicate a certain variable or whatever

[timid yarrow]

when i try to replicate events in my pawn they don't work

for an example:

[rare moss]

Oh you already tried something, why didn't you say?

[timid yarrow]

yep i did something. Sorry for not mentioning

[frosty heron]

Crossing over like that not gonna work

Multicast rpc run on every players machine

Not gonna work

Also if u want to pass something via rpc u need to pass the variable

[timid yarrow]

i didn't get it (sorry for my brain)

[magic gorge]

Multiplayer has many concept you need to see first

[frosty heron]

My advice is to ditch multiplayer if you don't have years of experience with unreal

Bp multiplayer is also very limited

[magic gorge]

Rpc, repnotify, authority etcc

You cant start multiplayer as first thing surely but mainly you cant if you dont know the framework

My suggestion at least

[frosty heron]

Rpc replication repnotify is the easy part too btw. Multiplayer goes way more than that

You can make multiplayer chess game or anything that don't depend on lag with bp if u can get past the replication part

[rare moss]

Multiplayer is very very complicated, especially if you are new

[frosty heron]

But if u doing shooter and real time action with bp, I would just make single player tbh

[timid yarrow]

So you guys are suggesting that i should use c++ when i am making multiplayer game?

[magic gorge]

You have experience or first project at all?

[frosty heron]

110% you can also ask the mod that does multiplayer game in #multiplayer

That's not to say bp multiplayer is impossivle

It's suffice for certain edge cases

[rare moss]

Well you could but it sounds like you currently have trouble with general multiplayer concepts atm, maybe make some tiny test projects

[timid yarrow]

It's not the first project but the previous projects that are made by me is so simple

[magic gorge]

Ive done a simple multiplayer game in full bp, its possible infact and im a junior we can say 4 years on ue

[rare moss]

Were they multiplayer?

[timid yarrow]

nope they were singleplayer

it's my first time to try multiplayer and i unsucceed

[magic gorge]

But as starter project i would say its a waste of time imho, or at least surely you learn something but its lime making a mmo as first game i think you should try to learn other stuff first

[rare moss]

Maybe its a good idea if you are dead set on multiplayer to make some very tiny projects with multiplayer to learn single things

[rare moss]

Making an mmo as a first game is such a bad idea lol, im following someone on twitch whos doing that, although tbf they have not actually made it multiplayer yet, they are trying to pitch the idea first so they don't actually need to do the network programming (which is smart ofc)

[magic gorge]

Yeah thats what i was saying, i was like that too but because i had no knowledge

[rare moss]

But if the pitch doesnt go well they plan to make the multiplayer themselves which I can only imagine the chaos that will be

[rare moss]

Well this guy is very dead set on making this game, regardlesd of what happens

Hes already been working a year, but this is getting more offtopic lol

[magic gorge]

Its easy to unsucceed if you dont know how it works, player controllers are only on server, and you have only your own on client, ui is present only on owning clients, i could write soo many things but you have to know how to move, where stuff exists and where doesnt, what you can call from client and what on server, etcc, i suggest watching the docs on how to make multiplayer experiences

[frosty heron]

Sounds like a scam tbh. If someone gonna pitch in mmo at least u want to see the networking part working

[magic gorge]

Mmo with dedicated servers which is a pain

As first thing is like a joke to me

[frosty heron]

Real mmo take a lot of software enginers

[magic gorge]

As i know you have to compile the actual ue5 to make dedicated server stuff well

[rare moss]

Yeah I know, but he wants to pitch his idea with a year of work he already put in to get money to hire the people who can actually make networking

I can verify that he has been working on it for the full year like he is putting an absurd amount of effort into this

[magic gorge]

Anyway, if you still here, i hate many tutorials but at least watch how the multiplayer framework works, whats on server whats on client etcc, you can also watch the ue docs online, it has everything, then you can see how to replicate stuff, and start with small things, then you can go on advanced stuff, my opinion, its your journey so you do what you think ita best for you

[rare moss]

Agreed

[frosty heron]

Youtube tutorial is bad in general but for multiplayer is even worse

[timid yarrow]

i watched some tutorials and they all do the same thing

[frosty heron]

I seen ppl spawning actor with multicast and everyone was thinking him in the comment section

[timid yarrow]

I watched them on youtube and they were doing same thing

[frosty heron]

Some tutlrial is good like delgoodie but in general most bp multiplayer is a scam

Like sprinting using cmc in blueprint...

They never test it with actual ping. The moment lag is introduced the game is unsurprisingly broken

[magic gorge]

Agree but some simple things can save a bit, like just whats on server and on client, some basics, even because actual frameworks doesnt need to be used specifically like ue describes so its all a “this is how i do it”

[timid yarrow]

what is cmc? I've seen it somewhere in reddit but i didn't get what is it

[frosty heron]

There are a few that is good but those are already pinned in #multiplayer

[frosty heron]

Character movement component

[magic gorge]

Yes

[timid yarrow]

oh sorry 🤦‍♂️

[frosty heron]

Prob best to read the pinned articles by exi and wizard cell

Those are the best gem u can get to start with mp

[magic gorge]

Good luck anyway

[timid yarrow]

thank you for all yours suggestions

[magic gorge]

Dont surrender hahaha

[topaz gazelle]

Is there a way to use Event Tick selectively? Like if I want to draw a line trace on keypress but not all the time?

[random pulsar]

can someone join the vc i have a quescion about inheritance,parent-child

[topaz gazelle]

I COULD do this but I'm just curious what alternatives there are

[versed sun]

Event Dispatcher

Timer

When you set Condition to True, Call Event or function

[topaz gazelle]

doesn't an event dispatcher just call the function once though?

[solid needle]

Hey everyone, I have a synty pack I'm using and wondering the best way to RANDOMIZE a bunch of aspects of a character (name etc). I am using arrays with the static mesh, mateirials, name etc and picks at random but is this good for memory having all those references not being used

[topaz gazelle]

Looking to enable/disable the tick function on an event

or flag

[hushed pewter]

Set Actor Tick Enabled, if your looking to disable the whole class.

[topaz gazelle]

I was concerned using that node would affect other parts of the class beyond Event Tick.

[hushed pewter]

Well yeh it should stop physics and such, anything that uses tick.

Using a single bool on event tick isnt too bad. If you're super concerned around performance you could make the function in c++

[undone bluff]

set actor tick enabled does not affect any components or physics (physics don't run on tick)

if you need event tick you can do it in a component and toggle that

[undone bluff]

you want to linetrace every frame only while the key is held down?

I have an interaction component that linetraces every frame and I just deactivate the tick when it's not needed

[frosty heron]

Enhanced input -> triggered should run every frame

[undone bluff]

though I want outlines when you look at something so it is running the majority of the time

speaking of, currently, I compare the new hit result against the last one (with an outline) and if it's a different actor/component I remove the outline from the last one

is there a better way to do it

[magic gorge]

Tick optimization has a big depth but disabling tick doesnt disable physics calculations which are managed by other components, the only thing tick is related in physics in an actor is for tick groups, which is a very deep optimization that i dont think many of you need

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/Actors/Ticking/

This is explained here but not your case, just for the misconception that was given

Tbh i would do like he said with trigger on enhanced input or the timer, disabling its ok but doesnt work if you want to use tick for other stuff

[magic gorge]

Yeah i used to do like this, i think its easier like i send now, wait a moment i send a picture on how i did it

its taking a moment to open the project hahahah

[hollow meteor]

Why does this print "Server: NO MOVEMENT" but can my clients still move around freely? I expect the server to block the client from moving because of this. How can I make sure a client doesn't move?

[hollow meteor]

Adding this doesn't do anything either

[magic gorge]

im not an expert on multiplayer, im still learning it, anyway i think you have to run a "run on owning client" event to disable input

like on disable input you run a "run on owning client" to do disable input

not all the event

[hollow meteor]

but we shouldn't trust user input - i can make the client perfectly not send input based on state, but if someone runs a hacked client the server shouldn't allow movement

[magic gorge]

the thing is that you are deciding when the player cant move but you are setting it on the server not on the player, player doesnt know if you dont replicate it, the server should validate inputs

i think posting on #multiplayer have better experts tho

[hollow meteor]

well thats my point exactly - I'm setting the servers' client movement input to "disabled" - so I would expect my clients to try and send input but the server shouldn't allow that (and the clients should look all jittery, snapping back to the servers' actual location)

right now i can see my clients moveing smoothly on all clients 😬

when I run "AddMovementInput" on the client, and the server receives that, it should say "nope - your input / movement mode is disabled, i disregard your movement request"

(thats why I've put the "switch has authority" in there, to test)

[magic gorge]

btw has authority shouldnt change anything

because the event onpossessed is a server only event

you can see it on the icon too on the event

[hollow meteor]

yeah the input is hooked to 2 things (possessed on the server, on rep state on the client)

[magic gorge]

oh gotcha

[hollow meteor]

so yeah I'm trying to figure out how to make the server authoritive in not allowing input basically 🤔

[magic gorge]

btw you might need to watch a bit better also the multiplayer framework, i mean onrepstate is called where and when?

[hollow meteor]

onrepstate happens on clients only when the state is changed (the messages show that it works in time)

[magic gorge]

its not a replicated to server event etc... its not well made, also if the state changes if you dont use repnotify might be not in sync with others if has some logic

[hollow meteor]

this is what it shows when I remoev the switch has authority, and I can now indeed not move the character from the client

[magic gorge]

ofc, the disable input is called on client this time

[hollow meteor]

wait, i can -_-

[magic gorge]

depends on how you do it, i cant understand whole code like this

[undone bluff]

I'd appreciate that

[magic gorge]

It did open now, i send

https://blueprintue.com/blueprint/pxqp07dk/ for interaction trace
https://blueprintue.com/blueprint/5letaqdb/ focus

[marsh pilot]

Currently I'm trying to "filter" an array by if a boolean variable of any item in that array is true. Is there something I can use to do this or do I need to build it myself?

[timber crystal]

hi guys why the enemys stop moven?
they have the same collision settings like my player character

screenshot of the trigger tutorial text box also in my post

[magic gorge]

I do like this basically, I just have the linetrace, i save the actual interactor for the call for Interact event, then I call the interface SetFocused which has a retriggable delay, that means that if in that 0,1 seconds its not called again it just automatically runs what after

Because it keeps retriggering so it doesnt complete until i stop focussing that

if you did like you said you should on the does not implement interface also call a function to remove the outline etc... or check if its a different one if it is then remove the other outline and add to the new

also trace channel TraceTypeQuery3 is a custom Interactable trace channel i made that didnt get copied

[magic gorge]

did they move previously?

[timber crystal]

yes normaly they move

when i set the collision of the trigger box for the text off they move like fish in the water

[magic gorge]

Not sure, I might just iterate on them dont think its a filter function in BP

[magic gorge]

Sorry I dont understand

[undone bluff]

ah so you use a retriggerable delay, that is cleaner but it still feels icky 😔

[timber crystal]

Yes, they move normally like fish in water without the trigger box from the tutorial text

[magic gorge]

mmmm.... something with collisions settings?

affect navigation?

i have never done anything 2d related so i dont know if you use navmesh volume in case the collision might affect navigation

otherwise might be the actual collision settings that blocks the enemy and overlaps you

[timber crystal]

Yes, that's why I photographed the trigger box and its collision settings

If only they had the same settings in their collisions as the player character...

Do you think its because the line trace of the enemys?

[magic gorge]

oh didnt see the collisions 😛

[timber crystal]

from the enemys? but i think if they have the problem why the player character dont have the problem

becuase my player can move insinde

*inside and so

[magic gorge]

you have to debug what they hit with the linetrace then if you use a linetrace

[timber crystal]

i use a line trace for the enemys maybe its because of that ?`waht kind of info can i give you to get help ^^

[timber crystal]

ok let me check

[magic gorge]

also try to set overlap only on the class you want to overlap and ignore others

like pawn, you dont use destructibles, or just visibility camera even if it shouldnt be a problem

just cleaner

[timber crystal]

okok i set now the line trace for duration but cant see it ingame

[magic gorge]

also if you think it might be collision you have to try to set all to ignore, then see if it's the issue if its not its not collision relatedc

[timber crystal]

ohh no sorry i see the line trace

[timber crystal]

yes thats it when i use ignore all collision they move

but then also my player cant overlap it

no text ...

[magic gorge]

now try with overlap pawn

[timber crystal]

ok they move now but no text because i dont now why?

[gentle urchin]

Enable / disable tick, gate , branch... typical flow manipuøation tools

Oops, im late to the party.

[magic gorge]

when does the text appear?

[magic gorge]

[timber crystal]

im not sure i mean the player has also a Pawn as collision

i try it with all collsion enabeld types... but they block the enemys by movement

very tricky problem maybe i need to ask my teacher next weekend 😭

[marsh pilot]

This is what I was able to come up with

[lavish barn]

I am trying to follow a tutorial and cannot see the option for the Item pin.

[magic gorge]

On the create node?

[lavish barn]

Yes

[magic gorge]

Idk

[magic gorge]

The variable must be instance editable and exposed on spawn

[lavish barn]

How do I do that?

The guide says to expose on spawn but there is no option for this in the details of the variable

[magic gorge]

Depends on what you have to do you can do a helper function that does that instead of creating an array, like getUnderConstruction pure function and return the array which id essentially a local variable to return at the end of for loop

On the variable under the type should be present 2 tick boxes

Instance editable and expose on spawn

[lavish barn]

This is what I see

[magic gorge]

Is that a variable on the widget itself or on a function on the widget?

[lavish barn]

On the widget itself

[magic gorge]

Im not sure thats the right window

[lavish barn]

Is there another window to create vairable

[gentle urchin]

Show the entire window

So we atleast can make better guesses

[timber crystal]

NP but god bless you for the try to help 🙂

[lavish barn]

This is the guide

On another widget I am trying to create this one and feed in the item so it knows what to pull

Hope that makes sense.

The option is there for other types but not this one

[magic gorge]

Maybe thats an issue on that variable type

What class type is that

[lavish barn]

USTRUCT

The file needed Blueprint Type for some reason

I can see it now.

[tidal nebula]

Hey can i dm u

I wannaa ask u something

[lavish barn]

Sure

[tidal nebula]

About the blueprint

[gentle urchin]

Hmmm... tablerowbase....

A workaround is to just make a settter function for itz and call that right after creation. Whatevers on construct that relies on this info can just be updated in/ after this function

[wispy badger]

Why isnt my screen mode getting changed?

when I put Print String at the end of the cycle (after Get Game User Settings), it prints the value correctly but it doesnt want to set it

[gentle urchin]

Musnt you also apply ?

The new settings...

[wispy badger]

Oh, right. Adding this node worked. Thanks!

[north lynx]

Hi!
I want to make, that the player stands still, but the camera rotates 90 degrees when clicking the button.
At first I wanted to make that using Timeline, but that's not working
Any ideas? I'm new in UE5

[leaden dock]

when i want to line trace in a UObject blueprint function, what exactly do i need?

a reference to the world? but i cant find a way to pass a reference to the world

i can pass a reference to the actor, but the actor alone doesnt seem to enable me to make a line trace

[undone bluff]

to rotate 90 degrees you first need to know your characters initial rotation and add 90 degrees on the z axis to that. If you want the rotation to be smooth you drive interpolation using a timeline

[gentle urchin]

You can have an actor that has a function that does the teace and returns the result

[leaden dock]

yeah that makes sense

[gentle urchin]

Or give the uobject world context

C++ if so

[tight pollen]

I want to use "soft object reference", if I use it on blueprint, will it help?]

[wispy badger]

How could I reuse a blueprint in other blueprint?
I'd want to transform these nodes into a function or something that I could hook up to

[wispy badger]

Okay I found something. What is a difference in converting these nodes to a macro vs converting to a function?

[lunar sleet]

a function needs to run in one tick. Macro will let you use latent actions

there are other differences but that's the main one

[wispy badger]

whats the difference between these 2? What do you mean by latent actions?

[lunar sleet]

things that take longer than one tick.

a tick = a frame, so depending on your framerate it'll be 1/120 , 1/60, etc.

[wispy badger]

in this example it would complete in one tick I guess

[lunar sleet]

then function is fine

[steady night]

hey guys need help how would i make the linetrace go towards middle of screen :/?

[lunar sleet]

you could maybe try get viewport size, break the struct and divide the X and Y by 2

[steady night]

it starts based on players rotation

@lunar sleethm and then ?

[noble ledge]

Does a "DoOnce" node only apply for each function call or is it during the entire life of the object that holds the function?

[lunar sleet]

once per runtime, until Reset

[noble ledge]

by runtime are you referring to runtime of the function or entire program?

[lunar sleet]

when you hit the Play button

the entire program

[noble ledge]

ok thanks

[wispy badger]

nevermind, I cannot use function. I need to use macro

[lunar sleet]

then you'd plug that into your end location, but you'd need a Z. but if by center of the screen you mean what the char is facing, then better to use the fwd vector

[steady night]

well i mean something like this ? i need to * with forward vector also somehow right

[lunar sleet]

like I said, it depends on what you mean by center of the screen.

[steady night]

yeah well baiscly i want it working like a 3rdperson shooting settup

shoot at crosshair*

basicly

[lunar sleet]

if you mean from the char's perspective, then just get the char's fwd vector, x by how far you want to trace, add it to the char's location and that's your goal location

[steady night]

so not linetrace towards the player hud center really*

well i want the rotation included also i mean

[lunar sleet]

fwd vector rotates with the char

it's where the capsule is facing iirc

[steady night]

like this , im my head it would linetrace from the camera straight forward right

[lunar sleet]

no, you need to add the result of the multiplication to the current cam's location

feed the Sum to the end goal

[steady night]

@lunar sleet getting closer :/?

[lunar sleet]

read my msg again

[steady night]

ok add

aye that got it working 😛

was obvious

thanks

[wispy badger]

How can I make a "motion blur" option in a settings panel?
I have a checkbox for enabling and disabling a motion blur but how would I connect it to the actual PostProcessVolume that exist in a different level?
How could I save UI values to the other scene?

[undone bluff]

I just use execute console command r.MotionBlur.Amount

[wispy badger]

Thats not flexible tbf

What about aliasing? What about vignette? If I'd want to configure every PPV property, I cannot use console commands

[plush ridge]

Layered blend per bone (spine_01) causes the affected bone(s) to scale to 0, no parameters in the node fix this — any ideas?

[undone bluff]

I apply whatever I can with UGameUserSettings

it has anti aliasing quality

but setting the method? console commands

turning on DLSS? console commands

[wispy badger]

What about custom world settings? You cant use console with that

[undone bluff]

aren't world settings and post process all just overrides of project wide settings you can set from the console?

I think so but might be wrong

[wispy badger]

I dont know

Im a nooby at ue

[undone bluff]

but I got all the settings I need that way at least

[wispy badger]

I dont want to go into the console's rabbit hole if I dont have to. I'd like to use something else

Something more transparent

[undone bluff]

UGameUserSettings can do a lot and helps with saving/loading

I don't think you can apply other settings without console commands though?

[wispy badger]

You mean GetUserSettings? Yeah, I do use it for vsync and resolution as that is the only way to actually set these properties

[undone bluff]

in blueprints at least

you can of course adjust post process on a camera or volume, you'll just need to get a reference to it in your instance where you load the settings, but adjusting the project wide post process seems like the better approach to me

any other post process settings are just an override of that

[wispy badger]

The thing is, the options would only be available once in the main menu. No dynamic changing afterwards. So I cannot get the reference to PPV because it doesnt exist yet

[undone bluff]

it doesn't matter where you set the setting, you just apply it when the level loads

I think for settings it's a good idea to store them in a json config file

you can do that with blueprints

[wispy badger]

Redundant for my use case

[undone bluff]

there's a plugin called "json blueprint utilities"

[wispy badger]

How would I save it at all?

[undone bluff]

^

if you don't need saving store settings in the instance

[wispy badger]

Apart from creating any files

[lost wolf]

in a class maybe?

[undone bluff]

save game object but they create files as well pretty sure

json is just nicely editable as you'd usually want settings to be

[lost wolf]

you dont need to write a file every time you click a setting, you do that when you click on save settings

[wispy badger]

It would need to be a static class but that would seem like a lot of trouble, no?

[wispy badger]

Im not creating an fps game where setting up configs is the core functionality of a game. I want a small settings system that can be saved throughout all levels

[wispy badger]

I dont want to create a file at all

[undone bluff]

well, then you cannot save?

the data needs to go somewhere

[wispy badger]

The data can remain in the app. Not saved anywhere but in the memory

Thats all I need. Thats all I want

[undone bluff]

then put it in the game instance

[wispy badger]

Instances would reset when you change levels, no?

[undone bluff]

no the game instance persists throughout the entire session

[wispy badger]

Okay, how would I save it in the Game instance then?

[undone bluff]

add a variable to it, set it in the settings and get it wherever you wanna manage to volume

[wispy badger]

Hmm, okay. Will try that

[ancient siren]

anyone know why?

[silk cosmos]

Where are you calling the begin play

sorry i got it to work

[fickle flame]

does anyone know how to make my NavMeshBoundsVolume show? Everywhere I look says to push P but when i do nothing happens

[turbid pecan]

Ugh my brain ain't braining. Can someone help me cross the road here?
I have two game modes, there's a small chance I might have a third eventually. What I want is to have a pure function that returns whatever the current game mode is being used in the level. So far I have what's in the screenshot, however this is ugly and forces the caller to then figure out what output to pick. What I was hoping to do is to return just a generic reference to whatever the game mode is from this function. Now.. if GameMode vs GameModeTown are diff types for that intent, I have no idea how to go about checking which one's being used and only returning that as a generic ref that a caller then can rely on as a single output from this function..

Unless I do this..

Hmm..

[lunar sleet]

#gameplay-ai question but you have to click the empty space in your level first. And if it doesn’t work go to Build -> All Paths first

[fickle flame]

ok sorry and TY this worked

[undone bluff]

P is just the keybind for the showflag

oh wait it's answered

[fickle flame]

yeah bu appreciate it!

you guys in this disc are awesome fr

[undone bluff]

but yea you can set it with the console and the show menu

[fickle flame]

ok ill have a look into that!

[turbid pecan]

Hmm yeah the cast to game mode generic node doesnt get the mode

sadly

[late venture]

Hello all, a quick question, is it an obligation to Cast To BP_Hero to get my vars there to bind to a text in a widget ? It seems I can't use Interface in a BP_Widget to get my vars, i don't like this cast technique, if someone got another solution, thanks !

[undone bluff]

use the native HUD class

it gets instantiated anyways

mine creates the hud widget and manages it, and I communicate with it using an interface

you can also get a reference to the HUD from the player controller

so it's easy to access

[late venture]

Ok i'll try a HUD Class, thanks

[late venture]

Or i'll cast once and make a reference, good to start, will see later the optim

[flint blade]

Hi All - probably a simple thing, but absolutely driving me nuts. How do a get a reference path to my selected actor? For example for my selected actor, it should return "Content/Test/TW/Wet_Well/Cassion/WW_CAS_L8" , but instead it returns "[StaticMeshActor_UAID_18C04D91DB00C7DA01_2002680411] /Game/ThirdPerson/Maps/ThirdPersonMap.ThirdPersonMap:PersistentLevel.StaticMeshActor_UAID_18C04D91DB00C7DA01_2002680411".

Does anyone have a link to any youtube vids or tuts for modifying an aactor/components height and shape? Im trying to somewhat morph a wall after certain triggers and cant seem to quite figure it out

[grim meadow]

Quick question i ran into an issue were suddenly some of my actors dont work any more. but just one node. Spawn actor. I thought it might be some weird stuff like a thing not loading or a bool unchecked. But when I just spawn actor from class on begin play it fails (nothing else just that). I then try it on a new empty actor and it some how works as it should. any idea if this is a known issue. or if this is a corrupted file in some way?

[zealous moth]

add print strings and see if all steps are printed. If they are but something fails, reproduce it within the same project in a fresh new actor. Sometimes the cache is corrupted and you cannot recover it.

@frosty heron have you had any luck with the "push collision" topic since last time?

[frosty heron]

Never had the chance to touch it. I'm not touching unreal till I finished 26 chapters on learncpp.com

Altough I thought you figured it out?

I think you tried add impulse on tick, does that do the trick?

[zealous moth]

give game modes a tag - get game mode > get tags > switch on string
^ scrap that, game modes cannot be tagged. You could have a parent with a tag variable and the children will inherit and have their own tags

[zealous moth]

it did and I refined it by using the weight property. So now it checks if weights are similar or not and then the velocity

[grim meadow]

@zealous moth thats the wierd thing i tried that with the print strings everything checks out. It says actor is just invalid, obviously it wont spawn if invalid. but why is it invalid? That's why it just tired on begin play spawn actor and only that and it still does not work. and on a fresh actor its fine.

[zealous moth]

if it's an actor difference, then the cache is corrupt

scrap the bad one and use the new one

an no, you cannot recover bad cache, I tried

[grim meadow]

hmm, shoot there is a couple of actor that are having the issue and they are a bit complicated. I am sure i will bite the bullet if i have to at the end. Maybe its from me zipping it up and saving a back up to g drive?

[silk cosmos]

Question for anyone thats familiar with common ui. Ive set up my input data to use my click and back actions that are defined in my input action data table and my input data is then assigned in my project settings. All of this is set up correctly - I've triple checked it at this point. The back action is working correctly for the key I've assigned it to, however the click action is not. I have set it up to work with "Enter" , but for some reason its always using the default of "Space" and "Gamepad face button bottom". Even the common ui overview live stream from Epic that was created over a year ago wasnt able to get the click action to work lol. Is there possibly a setting im missing somewhere or is this just a bug that hasnt been fixed? The back action is working fine, no matter what key I assign it to. Its only failing to work with the click action.

[frail onyx]

Anyone know how to make it i can have certain buttons be disabled and i'd have to lets say interact with something else to allow the button to be interacted with but some other ones are able to be interacted with from the start? I was using this tutorial for a key and door system but instead of using a keys for doors im using buttons for doors https://www.youtube.com/watch?v=Bcle9sSS4Oo

basically i just want to have one button that's is sparking and not functional, but all the other buttons are working, and if i turn on say a generator or something it re allows me to interact with the button and stops it from sparking

[undone bluff]

button has a state dictated by a boolean, if it's true allow interaction with the button

generator activates button, button activates door, you can do that with one interface function

[frail onyx]

ok i have the boolean for IsFunctional, do u know how i can make this work separately with each individual button, im kinda new to learning unreal so im not exactly sure how to modify my existing bp/buttons to make it work

[undone bluff]

is it not separate?

every button you place is its own instance

[frail onyx]

uhh im not sure i just have one bp for my button and at the bottom is how i make them only work for the door its assigned to

[undone bluff]

yea those are three instances

if you change the variable in one of them it won't affect the others

[frail onyx]

wait where do i change the variable in one of them? if i change it in the bp it seems to affect all of them

[undone bluff]

if you change it in the class BP_Button you set the default

when you drag the class into the level editor you have an instance

you can change the initial state of public variables in the detail panel like you're doing with the Door reference for just that instance

[frail onyx]

OHH do i need to set the variable to instance editable and expose on spawn to checked?

[undone bluff]

the BP_Button in your level is basically a child class of the BP_Button in the browser

each instance is a unique one

[undone bluff]

the little eye icon

[frail onyx]

ok

thanks that got it to work

[undone bluff]

you can abstract your interface more, instead of press button you can just have an activate function and every actor can interpret it differently

e.g. when you activate the button it allows interaction and when you activate the door it unlocks

only make specific distinctions when you need them

how exactly is a matter of preference, but having a unique function for every little thing gets messy real quick

[frail onyx]

oh so instead of making like a bunch of different functions like press button for buttons or switch lever for levers ect. i can just make one called like activate on each bp? and assign them to different bps that they can activate?

[undone bluff]

yea using such abstractions you can stay flexible and use any kind of switch to activate any kind of device

all switches would just send out an activate interface call and all devices would implement it in their own way

[frail onyx]

ok nice! So basically it would be like, i'd have a door with the activate interface and in the button bp i'd have the Activate function with the target as the bp door variable, and on the button bp i'd select the door id want to communicate with, then on the button i'd have the activate interface also and in my generator bp i'd have the activate function with the target as the bp button variable?

hopefully I'm understanding this correctly lol

[undone bluff]

Yea you can actually just make the door variable a generic actor reference and call it "target"

[frail onyx]

like this right?

do u know why it says get door on the bottom still though?

[undone bluff]

Search results probably just don't refresh

[frail onyx]

ok

Tysm for the all the help!!

[wanton hemlock]

heya, sorry for the question but my brain is fizzled out and I now turn to others for help. I'm trying to set up a blueprint for an actor that basically checks if a certain actor is present during a level. And if the actor is present it does nothing but if the actor isn't it creates said actor until it doesn't exist. any tips or suggestions?

[main lake]

I'm not sure to understand.

[bleak mason]

this is a quiz and the correct answer is array 0, if the player picks anything else i need the engine to act as if they've pressed 1 (which is already mapped to take damage)

it should be really simple but idk which nodes to use 🙏

[wanton hemlock]

sorry um, the best way I can try and make sense of it is like you are trying to see if a box is in the level. when this box disappears it should just create another box in it's place.

[main lake]

What about having an event inside that box blueprint, called "Destroy" box, and when it's called you just hid the mesh and disable its collision, and enable it back when you need it ?

[main lake]

Just call "Apply Damage"

[lyric rapids]

all those squares are seperate objects, in blueprints how would i get the vector3 location of each square and add it to an array

[bleak mason]

the condition is what im having trouble with. it should be this but idk how to script it. sorry for the noob question i know its such a simple thing to do 😭

[main lake]

Where do yo detect which answer the player chose ?

[bleak mason]

it doesnt detect yet. thats what i need to do. i assume it'd be happening under condition

[main lake]

Get a ref of your parent static mesh > GetChildren of it > ForEachLoop through that array > In the loop body, get your element through the pin given by the for each loop and use the "GetLocation" node > Save it in the array you want

[main lake]

How does the player chooses ? Is it a UI thing he needs to click on or he needs to write the number somewhere or something else ?

[bleak mason]

oh yeah it is a ui thing he needs to click

thats what it looks like. first one is the correct one

[main lake]

Create a variable on your BP_Character of type integer and call it something like "answer", and on your UI blueprint, when he presses a button, you get the player character > cast it to your BP_Character > Get the "answer" variable > Set it to the value you want.

Then in your BP_Character where the condition you showed me above is, you do > If "answer" == 0

[gentle urchin]

Isnt that mostly overriding some bone rotation?

Why is my Widgets Acting like this ?

the first screen is in Editor

the 2nd one is in game

Sizewise its all messed up ??

[gentle urchin]

perfect res vs imperfect res / scaling

[steady night]

yeah but how can i adjust that or whatever

aeverything is default

DPI scale 1.0*

set to 16:9 1920x1080

thats what im testing on also

[gentle urchin]

pixielsnapping also doesnt help

they even seem to be unevenly distributed , which doesnt help imo

right and left side...

i'd keep them all the same size

and adjust the border so it fits

[steady night]

they are 😮

[gentle urchin]

they're definetly not

[steady night]

oh true mb

[gentle urchin]

see how scewed this is

[steady night]

yy left was 9 right 8*

[gentle urchin]

intelligence is 6th row, and matches with defense, which is 5th row

9 is also just a tiny tiny size

especially if scaled down further

the res shown in editor is way higher than what you have in game

like... its probably full hd at any scale ?

the "0" is 74 pixels across in editor vs 8 in game

not sure if you can make the edtitor look like it will do at a given res in-game ?

[steady night]

i mean it should ?

[gentle urchin]

It clearly doesnt

[steady night]

yeah but this is weird

[gentle urchin]

it's common nevertheless

common pitfall

[steady night]

aye

[buoyant mica]

Hey blueprints channel hivemind. I'm super new to UE (just started back in the beginning of January), so I'll try to articulate my question here as best as I can, but I apologize if the way I'm describing it is off. I'm mostly just looking to be pointed in the right direction of where I can learn how to do this myself.

I'm prototyping a game where the main mechanic is you have a cat which can hunt small animals, and you need specific animals to solve puzzles. The levels are set within urban places like a subway station. You'll tell the cat to go hunt and it'll start to slowly pathfind its way to a spawn point which has an X percent change to spawn the particular prey you want.

I tried looking for tutorials on things like getting a dog to go fetch, but there's not much out there for things like that. This is all very much inspired by Rule of Rose, if that isn't immediately apparent lol.

Anyway! I appreciate y'all. I hope this isn't too ambitious in scale for a first project.

[lunar sleet]

There’s not going to be any tutorial for something that specific, break it down into different parts and you’ll be able to find solutions. For path finding, you might want to look into #gameplay-ai and EQS. There’s a pinned video there that goes over those, 5th pin iirc

[main lake]

I don't know 🤷‍♂️ as I never touched that kind of stuff. So if you know please guide me 🙂

[buoyant mica]

Sounds perfect! Yeah, I also found in the asset store that someone had made a dog companion that can fetch, but I figured it would be better for me to learn how to do this myself rather than buying it and struggling to make it work for my purposes without a solid understanding of what I'm doing.

[manic rover]

Good morning from Spain :). Could anyone tell me a course on YouTube to learn Unreal from scratch, please? I was following the gamedev.tv course but it's crazy to keep up with it :S

[lunar sleet]

Look up your first hour in Unreal, on the epic learning portal

And gamedev.tv is crap so good choice

[thin panther]

The portal also has some great projects like stack-o-bot, that are sort of guided follow along projects made by Epic

[manic rover]

Thank you.. .let's go to Unreal website! 🙂

I looked at those links but only saw things that seemed very advanced or C++ stuff. Sorry, maybe I didn't look properly :S. But knowing that there's a guide on the Unreal website, I'll go for that 🙂

Wow... I can see it in Spainish too! Thank you again, Laura! 🙂

Spanish

[buoyant mica]

Good morning from Germany 😛

[manic rover]

Last question about the paths of 'Video Games' or 'Film,' which do you think is better to work in? I really like both 🙂

[manic rover]

😛

[thin panther]

Just pick whatever you want.

If you are doing it as a hobby, why not both

If you want to go into industry however, you'll need to eventually pick a specialisation.

[modern elk]

Hello everyone, I have a question regarding the LaunchCharacter node. I would like to push the mob to a certain distance, so that it would be like pushing away, and not teleportation, and also without SimulatePhysics.

Any ideas on how this can be implemented?

[manic rover]

My idea is to enter the industry, or at least try, because I'm already of a certain age. I come from programming and was feeling a bit burned out. I like video games, and I like what is done in film with Unreal... that's why I wanted to consider the best path considering my real options (I'm 45 years old XD). Maybe working on my own... I don't know :S

[thin panther]

Definitely have a play around and see what you enjoy in that case then.

See if C++ in unreal is your jam, or level design, or game design. See if something in film is what you enjoy, then just hone that.

If you want to work solo, it's a bit different as you wear many many hats

[buoyant mica]

I think that depends on your goals and how much interactivity means to you. Of course there are games that are sort of a hybrid between the two because they really try to deliver a cinematic experience. But interactivity brings with a lot of unique considerations, such as game feel. Stuff that usually is fairly invisible if you do it right. If all that feels like a headache, then film is probably the way to go.

For me, I'm obsessed with all that stuff, so that's why I'm pushing myself to learn it.

(I'm an artist and not really a programmer. )

[manic rover]

"For me, I'm obsessed with all that stuff, so that's why I'm pushing myself to learn it."

Both things? I like both too, but there's a saying in Spanish that goes 'El que mucho abarca, poco aprieta'... I think it's impossible to translate :D. That's why I wanted to 'focus', but if the courses on the Unreal website are not very long, maybe I'll try both things. And I won't write anymore because I want to leave you all in peace! 😄

[buoyant mica]

Enjoy! That's the important part.

For now I'm working on coloring in some concept art before I get back to learning this AI pathfinding stuff.

[glossy bolt]

hello guys , when i use this node to move the actor throw projectile it snap the actor to last position not moving throw the projectile path it snap's it.

[wicked cairn]

Hello! I'm making a fishing mini game that occurs when fish is hooked, and want the player to have to click when a visual circle reaches an indicated spot around the fish to successfully capture it! Any suggestions on how I could get this done? Kinda like a rhythm game mechanic

[celest lotus]

any idea why i am getting an hit on surface, when i set the collision response of that actor as ignore. I m doing a sphere trace in a custom trace channel and the actor its hitting has the response of that channel to ignore yet its still giving the hit. Its actually a geometry brush if that would make any difference

[vestal jolt]

If I construct a UObject in Blueprint do I need to save it in Blueprint variables or anywhere so it is not garbage collected?

[fiery swallow]

IIRC you do need a reference to it somewhere in order to keep it from being garbage collected

[gentle urchin]

A hard pointer afaik

Not a weak/soft one

[vestal jolt]

mmm, I know how to create a weak ptr but how do you create a soft ptr?

[gentle urchin]

Soft object reference,

Can be picked from the dropdown menu where you pick ref or class var

Theres also soft ref and soft class

[wooden cave]

why its this not working? im trying to do a "slow zone" but the speed just doesnt interpolate it just jumps

[gentle urchin]

Is this on tick?

This looks wrong

You want. A static target speed

Not one that moves with the interp

Or you may not want interp at all

[wooden cave]

on overlap

with the trigger box

[gentle urchin]

Right

So you just wanna adjust the max speed

And let the vehicle act acvordingly.

[wooden cave]

when car overlaps with box = car slows down gradually

pretty much

[vestal jolt]

Is soft ptr in blueprints the same as TWeakObjectPtr In c++ terms or are they different?

[dire frost]

Nope they're different. Softptr is just a pointer with an asset path

Weakptr just forces your to check and claim ownership of the ptr before using it

[wooden cave]

i tried the "get max speed" and when i print the value its just says 0, (so it just wont work if i adjust max speed since car can reach 300+ with max speed at 0.0 apparently) so thats why im using linear physics

[vestal jolt]

Thanks for the answers guys

[gentle urchin]

how are you moving the car ?

[wooden cave]

chaos vehicle

[gentle urchin]

so it runs on physics

[wooden cave]

yes

[gentle urchin]

i would guess there's still some throttle limiter , if not speed limiter directly

[wooden cave]

the gear ratios its what limits speed of each gear

that + torque but

[gentle urchin]

and some rpm range i gues

[wooden cave]

but decreasing torque going 120 wont slow the car down

[gentle urchin]

correct

you'd need to apply brakes

seems there is a max speed

[wooden cave]

there is

a node, but cant find a value to change or anything related to that

[gentle urchin]

do you know any c++ ?

[wooden cave]

all i could do to limit is rpm/gear ratio/torque

[wooden cave]

i dont, no

[steady night]

how many here jhave released their own game ?

[gentle urchin]

ugh

[wooden cave]

what does that mean?

[gentle urchin]

not much atm

trying to see if there's anything we can add to grant control of this

it wouldnt slow down but

if you'd apply breaks on the slowdown while speed > maxSlowSpeed then it would all be handled

[wooden cave]

im tryna explore the braking when overlapping

but idk what im doing but doesnt seem to work

[gentle urchin]

there's basically just 2 things

we dont need this max speed really

[wooden cave]

interpolating are my enemies fr

[gentle urchin]

we dont need interp

[wooden cave]

then how can i make the 0.0 brake input to a 1.0 smoothly

tried the easy node too, but im too dumb for that tbh

[gentle urchin]

2 vars, a bool and a float

a function in the VehicleAdvPawn or whatever main vehicle bp you use

In the slowdown BP

another small function in the car bp

[wooden cave]

damn, tysm

imma look at it rn

[gentle urchin]

didnt work perfectly but

it's in the neighbourhood

[wooden cave]

yeah car aint slowing down, seems like i gotta check the main car bp to see why the throttle input its always 1

probs a error i made not urs

imma check all bp's just in case

[gentle urchin]

On Tick

On Throttle

works ok now,

I'd prefer not seeing the "jitter" from the speed surpassing the speedlimit and brakes hitting in but

[wooden cave]

it is what it is

[gentle urchin]

adding +1 to the tick one

fixed it

[wooden cave]

tbh imma copy what you did and then try to understand it so

[gentle urchin]

so it only breaks when the speed is above speedlimit + 1

Looks alright

this is if we are above the speedlimit while entering

[wooden cave]

i might need to check wtf i did wrong cuz my car just starts reversing on its own without overlapping xDD

[gentle urchin]

😆

Dont messs up > and <

[wooden cave]

yeah now it not moving by itself, i was missing the And boolean

imma check if everything works

yeah it works, ty i couldnt up come with everything myself

now ill try to add a lil math to the variable of the speed limit in the slowzone so i can convert the mph to kmh

[jaunty jolt]

I need to make a feature that manages the rabbits of all players in my game. Where should i make this feature?

Seems GameState

Or gameinstance?

Game mode?

[gentle urchin]

*1.62 iirc

1.609* mb 😄

[turbid pecan]

I might now the answer but how bad is it to do this:

Like this gets called every tick, I can't imagine this being a sane way of checking stuff

[gentle urchin]

Whats it worth to you

But theres an event any key already giving you this

[turbid pecan]

I just derped. I can grab the IA action and use the event

no need for tick

[gentle urchin]

😆

[wispy badger]

How can I get Game Instance blueprint in order to set custom variables in it?

the only Game Instance I have is a non-modifiable C++ class

[versed sun]

make your own

[gentle urchin]

Creatw a new bp subclsss ^

[wispy badger]

oh, well. Okay

[versed sun]

assign it in Project Settings

[wispy badger]

as the Default GameMode field?

[versed sun]

no, bottom Game Instance

[wispy badger]

Oh right, didnt go that much down

thanks

[versed sun]

Then you can Get and Cast

[wispy badger]

by the way, is there a way to get an actor from a level by reference without having to get all actors with the same class?

[gentle urchin]

Depends

You can set it up through a common bp

Usually you have some sort of interaction between two bp's if they are ment to... interact or react tho

How do the actors relate to each other?

[wraith wedge]

hey guys, does anyone know how I can fix the camera after the servertravel? I want to make a blackscreen immediately after the loading, but it always first show the whole map as you can see from a weird perspective

[wispy badger]

one is a main menu widget blueprint, the other is a post process volume actor in the level. The only relation these 2 have is that main menu changes the PPV settings like motion blur

[gentle urchin]

Ppv sounds player spesific

You could use game instance as the mediator

Then it survives swapping levels aswell

[wispy badger]

yeah thats why I need a game instance

[gentle urchin]

Doesnt survive termination of the game tho, so at some point you gotta sace and load

Personally id just skip right to the save / load

One less bp involved

[wispy badger]

I dont need to save these options anyway. They should only be remained in the same game session

so doesnt matter

[gentle urchin]

Ok

Then game instance is alright

[wispy badger]

Is it possible to check and uncheck a single setting in PPV? When motion blur is enabled, the Amount is checked with default amount. When its disabled, the Amount field is unchecked

I see I can only set settings with value but I dont see an option to even uncheck these settings

[charred vale]

hey all, why her feet stayn at place? i guess abp work correct and its related to blendspace itself but idk

[tranquil saffron]

When i start my game Unreal engine crashed, and this message show up. Can someone help me?

[wispy badger]

#ue5-general would probably be a better channel for that

Is there a better way to do this? Unparenting a widget and creating it again seems like a huge waste

[turbid pecan]

You know how some games have a "investigate" mode? Like you get to click on stuff with your mouse, but can't move or take any of the typical actions inherent to normal gameplay?

I tried making that, but its a bit of a bugger cause i want it to be on key press. But if I disable input on the controller on pressing that key, I cannot toggle it off cause - well, I disabled all input. What's a decent way to avoid this? Would it be possible to disable the movement enhanced input action temporarily or is there a way to disable actions with exceptions?

Or would a saner way to do this be something like:

1: Have one mapping context for normal stuff and another for interacting
2: Swap them on key press by using remove/add mapping context on key press

[uneven coyote]

Hate to be that guy the just joins and asks stuff right away. But for some reason whenever i try and make my drawers interactable they open fine with the key selected except they want to fall to the floor on opened instead of staying on the y and just pulling open. Any ideas? Do i need to constrain the drawers?

[spark steppe]

how do you open them?

if they are simulating physics you may want to constrain them, yes

[uneven coyote]

and that would be inside the drawers themselves what would i put for that in bp's? Never had to do this quite yet so my bad.

i did want to open them by clicking and pulling but had to settle with a simple f interaction lol

[plain hull]

whenever i change roll, pitch it also changes yaw. using setworldRotation. I want to fix yaw value at 0. Any leads please

[spark steppe]

i would disable physics on them and just set the mesh location in that case

[turbid pecan]

Yup turns out the best thing to do was swap IMCs

god bless my lack of unreal knowledge

[uneven coyote]

im bricking it lol physics were already disabled but now on start they all fall to the ground XD I shall go do studying on this topic

[young meteor]

Hey guys.

I'm trying to make a button with consistant edges on the left and right side. (hexagon theme)

I want to keep the inside angles at 120 degrees like shown in the picture.
I used a Hexagon.png image and draw it as a box with margins to not alter the left and right. Which works fine when I make it in its own simple test widget.

If I try to do it in my actual menu It looks like below though. How do I avoid this stretching?
I can NEVER figure out if I need to wrap it in a scale box, size box, both, none of them, or if it is an alignment option or something?

[lime basin]

I've marked my progress bar "Is Variable" but when I go to graph I cant find it anywhere

what am I missing?

[lofty rapids]

what bp are you trying to access it from ?

[lime basin]

widget blueprint

the same one

[lofty rapids]

it should be in your variables at the top left

you can just drag n drop it

[lime basin]

yea but its not

[simple echo]

Hey all,

I am trying to implement a sort of boomerang throwable weapon, where the weapon moves in a circle away from the player and back.

I have created a new actor blueprint class, but am unsure of how to move it is this fashion.

Any help would be greatly appreciated!

[gentle urchin]

You mark it as variablenin top right corner

[lime basin]

yes

[gentle urchin]

Not the visibility marker

[gentle urchin]

Compiled?

Try re adding it ifnso

[lime basin]

yes, could be because I define it in c++ before with meta "bindwidget?"

[gentle urchin]

I would probably investigate using a spline for this

[lime basin]

    class UProgressBar* ProgressBarWidget;``` like this

[gentle urchin]

Possible.. not sure tbh

[lime basin]

I found it

[eternal latch]

hello dear friends!
Actor with box collision somehow triggers event on all clients of session on begin overlap, even server if there is one, even if it is set to owning client ONLY.

don't know where to get from there, it is kind of weird behavior isn't it?
I am not quite new to the replication, but this is slowly driving me insane

[lime basin]

idk why its not in variable but gotta search for it here

its working I was just being stupid thank you for help 🙂

[wispy badger]

Is there a way to get a class of a reference when the reference doesn't exist yet?

this fails due to Get Class returning Unknown. I need to manually provide the class for Create Widget function. Any way to take it from the empty variable with a specified type?

[main lake]

Why do you need to get it through a variable when you can manually choose the class in the "Class" property of "Create WBP Options Widget" dropdown ?

[wispy badger]

What if the class changes? I'd have to manually replace it everywhere

[lofty rapids]

you can right click class and promote to variable, thats the kind of variable you need ?

[wispy badger]

Yea but then I would have 2 separate variables pointing to "the same" object

[main lake]

Then you can create a variable of type "Class Reference" and use that variable everywhere you want, so you can just modify that variable so it modifies stuff everywhere ?

[wispy badger]

Yea but then I would have 2 separate variables pointing to "the same" object

[main lake]

What do you mean ?

[lofty rapids]

what are you trying to do here ?

[simple echo]

Thanks for the tip!

[wispy badger]

first variable pointing to the object reference
second variable pointing to the object's class

[wispy badger]

I have a main menu ui. I want to reference options Widget from Main Menu and vice versa so I wouldnt create more than 1 instance of a BP class

[main lake]

Why would you have the first variable ?

[lofty rapids]

so you have two widgets and you want to reference each other ? put them in the HUD

[wispy badger]

so you have two widgets and you want to reference each other ?
yes

put them in the HUD
Its main menu panel. Both cant "exist" at the same time

either one or the other

[lofty rapids]

well then can exist, but just not show ?

[wispy badger]

yes

they should be both created but only one is visible at the time

[lofty rapids]

i'm not sure what you mean, you can create them both in the HUD

and access them from anywhere

and hide/display as needed

[wispy badger]

what do you mean?

[main lake]

the HUD class, is just a container that can receive as many UI Widgets as you want

[lofty rapids]

i have two widgets in a project, and i just hide one, show the other and vice versa

[wispy badger]

that would be too much of a hassle I think. I'd rather go with references

[lofty rapids]

it is references, they are just in the HUD so you can access them

[wispy badger]

I mean one references the other without having to put them in a separate container

[timid yarrow]

I know it would be a noob question but how can i detect the surface angle that i hit? I don't want to jump if the angle is bigger than 80 degrees. How can I do that?

So i don't want to jump on walls

[main lake]

Use the "Hit Normal" instead
